Bikas Saha commented on YARN-308:
---------------------------------
You would want to look at YARN-103 and related jiras that are trying to make
the protocol easy to use by implementing base libraries that hide the protocol
complexity.
The AMRM protocol is not a delta protocol but an absolute one. So every ask
request sends all outstanding requests to the RM.
> Improve documentation about what "asks" means in AMRMProtocol

> It's unclear to me from reading the javadoc exactly what "asks" means when
> the AM sends a heartbeat to the RM. Is the AM supposed to send a list of all
> resources that it is waiting for? Or just inform the RM about new ones that
> it wants?
